abstract
Rectangular turbulent jets (RTJ's) offer several advantages over conventional circular jets in matters of mixing (entrainment) efficiency and depth of penetration into the ambient. In this paper, we perform partially-averaged Navier-Stokes (PANS) simulations of a square jet at various scales of resolution. PANS results are compared with the mean streamwise velocity (MSV) of experimental data. Qualitative and quantitative agreement with experimental data is good. This paper demonstrates that PANS is capable of capturing jet physics. In the future, we will extend this work to include rectangular jets of various aspect ratios.
